RADIATOR AND PROCESS 0F PRODUCING-SME.

Application led July 11,1921. Serial No. 483,)876.

To all whom t may concern.'

Be it known that we, IRA S. CHAPMAN and CLYDE E. MORT, both citizens of the United States, the former residing at Venice, in the county of Los Angeles and State of California, the latter residing at Rialto, in the county of San Bernardino'and State of California, have invented a new and useful Radiator and Process of Producing Same, of which the following is a specification.

The object of our invention is to cheaply produce a radiator for air cooling of liquids which will have a very large e ective area and which may be very cheaply constructed. Such radiators are commonly used on automobiles.

Referring to the drawings which are for illustrative purposes only,

ig. 1 is a perspective view of one of the elements of our radiator.

Fig. 2 is va View as seen from the front showing the method of assembling these elements for the of a radiator.

Fig. 3 is a section on a plane represented by the line 3-3 of Fig. 1.

Fig. 4 is a view on an enlarged scale s'howing one method of securing the elements together.

Fig. 6 is a diagrammatic view of the method of plating.

In the form of the invention shown, elements l1 are provided, each member consisting of a rectangular copper tube having small protuberances 12 formed thereon. In assembling a radiator amultiplicity of members llare assembled, as shown in Fig. 2, the protuberances 12 registering and forming water vspaces 13 and 14 between the ele- 5 is a view showing an alternate ments 11.

. pleted radiator.

In practice, the members 11 are assembled between two outside sheets of copper 15 and 16. The assembly is made of sufficient length in the direction a to suit the height of standard radiators, the width b being preferably about 3, so that a plurality of these sectionsy formed as shown in Fig. 2 may be assembled side by side to make a com- The members 11 held between the members 15 and 16 are then placed on their side and the water spaces 13 and 14 are filled with wax 50, this wax locking the whole assemblytogether. The ends of the purpose of making a sectionh members 20 and 21 are then hung in an electro-platin bath 30 carried in a tank 31, as shown in fig. 6. A copper electrode 33 is also hung inthe bath 30, an electric current being caused to How between the electrode 33 and the section 32 through the electrolyte or plating bath 30. This causes the deposition of copper on the ends 2() and 21 of the ifarious sections 11 and the ends of the plates l5 and 16. This deposited copper is shown at 40 and 41 in Figs. 4 and 5.

It will be noted that the deposited copper extends in to the interior of the members 11 to a certain degree as shown at 43 and that it extends across between the elements 11 as shown at 42. Thus the deposited copper 4() joins the elements 11 solidly together and also joins them in a similar manner to the copper sheets l5 and 16. In some cases, we prefer to flare the elements 11 as shown in Fig. 5 in which case the protuberances 12 may be dispensed with. After the completion of the plating operation', the completed section 32 is heated, and the wax 50 previously carried in the Water spaces is thereby melted out. y When completed, each of the sections 32 consists of a practical continuous copper shell surrounding the spaces 13 and 14. The various sections 32 are then assembled to form a radiator, the upper portion of these sections being soldered intov a water tank and the lower end of the sections being soldered into a header in accordance with the usual practice.

We claim as our invention:

1. A method of producing a cellular, radiator comprising; assembling a multiplicity of metal tubes; casting a retaining material in the space between said tubes; electrically depositing metal to bind the ends of said tube-s together into a single section; and thereafter removing the retaining material.

2. A method of producing a cellular radiator comprising; assembling al multiplicerative relationship with each other; and electrically. depositing metal to bind the ends of said tubes together into a single section.

In testimony whereof, we have hereunto set our hands andseals at Los Angeles, California, this 30th day of June 1921.
